松辽盆地南部中浅层青山口组储层预测方法
|
摘要
本文针对楔状型地层提出二分法地震属性的提取方法,即在选定上、下参考标准层时间后,取其二者的1/2点处作为输出的属性点,如此递进细分。文中说明了这种方法的合理性和有效性,并在松辽盆地南部中浅层青山口组储层预测中进行了应用,表明了该方法的实用性和可行性。通过分析该区目的层段的沉积特征和油气成藏规律,确定了有利储层发育区,提出了建议钻探目标。
The dichotomy seismic attribute extraction method for wedge-shaped strata was proposed in this paper. At first the times for the upper and lower reference layers were picked up,then the middle time value of the two times is regarded as the time for the attribute points,and then the time pick-up goes further in more detail in this way. Rationality and effectiveness of this method were explained in this paper,and the method was applied in reservoir prediction for the shallow-middle Qingshankou Formation in southern Songliao Basin,and the practicability and feasibility of the method were proven in this paper. Through analysis of sedimentary characteristics and hydrocarbon accumulation rule for the target formation in this area,favorite reservoir development areas were determined and drilling targets were proposed.
